Fatigue visual analogue scale score correlates with quality of life in cancer patients receiving epoetin alfa (Sandoz) for chemotherapy-induced anaemia: The CIROCO study.

PURPOSE: Available tools to measure fatigue and health-related quality of life (HRQoL) in cancer patients are often difficult to use in clinical practice. The fatigue visual analogue scale (VAS) provides a simple method to assess fatigue. This study evaluated the correlation between HRQoL and fatigue perceived by cancer patients undergoing chemotherapy. METHODS: This was a non-interventional prospective study of adult cancer patients in France presenting with chemotherapy-induced anaemia (CIA) treated with epoetin alfa (Sandoz). Data were collected using an electronic case report form at study inclusion (T0), after 2-3 chemotherapy cycles (T1) and after 4-6 cycles (T2). RESULTS: The study included 982 patients from September 2015 to October 2017. Overall, there was a negative correlation between fatigue VAS and HRQoL. The overall haemoglobin (Hb) change between T0 and T2 was +17.8 % (± 18.1 %). Fatigue assessed by both patients and physicians showed a clinically significant improvement during the study. Global HRQoL also increased. CONCLUSION: Treatment of CIA with epoetin alfa (Sandoz) improved Hb levels, fatigue, and HRQoL, with a correlation observed between fatigue VAS score and HRQoL. Fatigue VAS could act as a simple alternative to more complex methods to measure HRQoL; however, further analyses are required to confirm this association.

Single-dose NEPA versus an aprepitant regimen for prevention of chemotherapy-induced nausea and vomiting in patients receiving moderately emetogenic chemotherapy.

INTRODUCTION: Non-inferiority of NEPA (fixed combination of NK1 receptor antagonist (RA), netupitant, and 5-HT3 RA, palonosetron) versus an aprepitant regimen was previously shown in a pragmatic study in patients receiving anthracycline cyclophosphamide (AC) and non-AC moderately emetogenic chemotherapy (MEC). In the MEC group a numerically higher complete response (CR: no emesis, no rescue) rate was seen for NEPA during the overall 0-120 h phase (NEPA 76.1% vs. 63.1% aprepitant). As NEPA exhibits long-lasting efficacy, this study evaluated a prolonged period up to 144 h, beyond the traditional 120 h post-chemotherapy. In this post-hoc analysis we explore the comparative efficacy of NEPA versus the aprepitant regimen in the MEC group up to 144 h, while also assessing the impact of risk factors on CINV prevention. METHODS: This was a pragmatic, multicenter, randomized, prospective study. Oral NEPA was administered as a single dose on day 1, while aprepitant was given on days 1-3 + ondansetron on day 1; all patients were to receive dexamethasone on days 1-4. Patients were chemotherapy-naïve and receiving MEC, with a subset evaluation of those with a risk factor for developing CINV (i.e., female, male <60 years, male ≥60 years who received carboplatin, or male ≥60 years with anxiety). CR rates were compared during the extended overall (0-144 h) phase. RESULTS: The MEC group included 211 patients; of these 181 were in the risk factor subset. Significantly higher CR rates were seen for NEPA than aprepitant during the extended overall phase for the total MEC group (NEPA 77.1%, aprepitant 57.8%, p = 0.003) and also in the subset of patients with CINV risk factors (NEPA 73.9%, aprepitant 56.2%, p = 0.012). CONCLUSION: A single dose of NEPA, administered on day 1 only, was more effective than a 3-day aprepitant regimen in preventing CINV for an extended duration in patients receiving MEC and in those with emetic risk factors.

[Postoperative radiotherapy in non-small cell lung cancer stage IIIA - N2: Focus and perspectives]. / La radiothérapie postopératoire dans les cancers non à petites cellules de stade IIIA ­ N2 : mise au point et perspectives.

Patients with resectable stage IIIA - N2 lung cancer represent a very heterogeneous population with variable risks of postoperative recurrence depending on the type of N2 involvement (unisite N2, multisite N2, bulky N2, extra-capsular rupture, incomplete resection…). This heterogeneity associated with the difficulty of carrying out prospective randomized studies with sufficient power in stages IIIA - 2, results in the absence of clear and consensual recommendations (except for stages IIIA - N2 resectable R0, since LungART and PORT-C studies). The objective of this article is to make an update on the place of postoperative radiotherapy in the management of stages IIIA - N2 following the publication of two recent randomized trials (PORT-C and LungART) but also compare them fort a better understanding of the current issues raised by these first published results. Indeed, these two trials do not find any benefit in terms of progression free survival and overall survival of postoperative radiotherapy but exploratory analyzes from these two studies seem to show a potential benefit of postoperative in some pN2 populations at high risk of locoregional recurrence (N2 multisite, N2 bulky…). In addition, the advent of immunotherapy (atezolizumab or pembrolizumab) and targeted therapies (osimertinib) in the adjuvant situation are redebating the place of a possible indication for postoperative radiotherapy in stage IIIA - 2.

Dietary exposure to acrylamide and breast cancer risk: results from the NutriNet-Santé cohort.

BACKGROUND: Acrylamide is classified as a probable human carcinogen by the International Agency for Research on Cancer but epidemiologic evidence on the carcinogenicity of acrylamide from dietary sources is limited. OBJECTIVES: This study aimed to investigate the associations between dietary acrylamide and breast cancer risk in the NutriNet-Santé cohort, accounting for menopausal and hormone receptor status. METHODS: This prospective cohort study included 80,597 French females (mean ± SD age at baseline: 40.8 ± 14 y) during a mean ± SD follow-up of 8.8 ± 2.3 y. Acrylamide intake was evaluated using repeated 24-h dietary records (n ± SD = 5.5 ± 3.0), linked to a comprehensive food composition database. Associations between acrylamide intake and breast cancer risk (overall, premenopausal, and postmenopausal) were assessed by Cox hazard models adjusted for known risk factors (sociodemographic, anthropometric, lifestyle, medical history, and nutritional factors). RESULTS: The mean ± SD dietary acrylamide intake was 30.1 ± 21.9 µg/d (main contributors: coffee, potato fries and chips, pastries, cakes, bread). During follow-up, 1016 first incident breast cancer cases were diagnosed (431 premenopausal, 585 postmenopausal). A borderline significant positive association was observed between dietary acrylamide exposure and breast cancer risk overall (HR for quartile 4 compared with 1: 1.21; 95% CI: 1.00, 1.47) and a positive association was observed with premenopausal cancer (HRQ4vs.Q1: 1.40; 95% CI: 1.04, 1.88). Restricted cubic spline analyses suggested evidence for nonlinearity of these associations, with higher HRs for intermediate (quartile 2) and high (quartile 4) exposures. Receptor-specific analyses revealed positive associations with estrogen receptor-positive breast cancer (total and premenopausal). Acrylamide intake was not associated with postmenopausal breast cancer. CONCLUSIONS: Results from this large prospective cohort study suggest a positive association between dietary acrylamide and breast cancer risk, especially in premenopausal females, and provide new insights that support continued mitigation strategies to reduce the content of acrylamide in food.This trial was registered at clinicaltrials.gov as NCT03335644.

Influence of the SARS-CoV-2 outbreak on management and prognosis of new lung cancer cases, a retrospective multicentre real-life cohort study.

INTRODUCTION: The SARS-CoV-2 pandemic has impacted the care of cancer patients. This study sought to assess the pandemic's impact on the clinical presentations and outcomes of newly referred patients with lung cancer from the Greater Paris area. METHODS: We retrospectively retrieved the electronic health records and administrative data of 11.4 million patients pertaining to Greater Paris University Hospital (AP-HP). We compared indicators for the 2018-2019 period to those of 2020 in regard to newly referred lung cancer cases. We assessed the initial tumour stage, the delay between the first multidisciplinary tumour board (MTB) and anticancer treatment initiation, and 6-month overall survival (OS) rates depending on the anticancer treatment, including surgery, palliative systemic treatment, and best supportive care (BSC). RESULT: Among 6240 patients with lung cancer, 2179 (35%) underwent tumour resection, 2069 (33%) systemic anticancer therapy, 775 (12%) BSC, whereas 1217 (20%) did not receive any treatment. During the first lockdown, the rate of new diagnoses decreased by 32% compared with that recorded in 2018-2019. Initial tumour stage, repartition of patients among treatment categories, and MTB-related delays remained unchanged. The 6-month OS rates of patients diagnosed in 2018-2019 who underwent tumour resection were 98% versus 97% (HR = 1.2; 95% CI: 0.7-2.0) for those diagnosed in 2020; the respective rates for patients who underwent systemic anticancer therapy were 78% versus 79% (HR = 1.0; 95% CI: 0.8-1.2); these rates were 20% versus 13% (HR = 1.3; 95% CI: 1.1-1.6) for those who received BSC. COVID-19 was associated with poorer OS rates (HR = 2.1; 95% CI: 1.6-3.0) for patients who received systemic anticancer therapy. CONCLUSIONS: The SARS-CoV-2 pandemic has not exerted any deleterious impact on 6-month OS of new lung cancer patients that underwent active anticancer therapy in Greater Paris University hospitals.

Dose-Intense Cisplatin-Based Neoadjuvant Chemotherapy Increases Survival in Advanced Cervical Cancer: An Up-to-Date Meta-Analysis.

PURPOSE: We set out to demonstrate the benefit of using dose-intense cisplatin-based neoadjuvant chemotherapy in terms of overall survival and progression-free survival. METHODS: We searched through MEDLINE and Cochrane Library databases up to May 2021 to identify randomized clinical trials comparing the benefit of using cisplatin-based neoadjuvant chemotherapy followed by local treatment with local treatment alone for the treatment of locally advanced cervical cancer. The PRISMA statement was applied. RESULTS: Twenty-two randomized clinical trials were retrieved between 1991 and 2019, corresponding to 3632 women with FIGO stages IB2-IVA cervical cancer. More than 50% of the randomized clinical trials were assessed as having a low risk of bias. There was no benefit of neoadjuvant chemotherapy on overall survival, but there was significant heterogeneity across studies (I2 = 45%, p = 0.01). In contrast, dose-intense cisplatin at over 72.5 mg/m2/3 weeks was significantly associated with increased overall survival (RR = 0.87, p < 0.05) with no heterogeneity across the pooled studies (I2 = 36%, p = 0.11). The survival benefit was even greater when cisplatin was administered at a dose over 105 mg/m2/3 weeks (RR = 0.79, p < 0.05). CONCLUSION: Even though radiotherapy combined with weekly cisplatin-based chemotherapy remains standard of care for the treatment of locally advanced cervical cancer, our meta-analysis makes it possible to consider the use of dose-intense cisplatin-based neoadjuvant chemotherapy when local treatment is suboptimal and opens perspectives for designing new clinical trials in this setting. Neoadjuvant chemotherapy could be proposed when surgery is local treatment instead of standard chemoradiotherapy for the treatment of locally advanced cervical cancer.

Adoptive cell therapies in thoracic malignancies.

Immunotherapy has gained great interest in thoracic malignancies in the last decade, first in non-small cell lung cancer (NSCLC), but also more recently in small-cell lung cancer (SCLC) and malignant pleural mesothelioma (MPM). However, while 15-20% of patients will greatly benefit from immune checkpoint blockers (ICBs), a vast majority will rapidly exhibit resistance. Reasons for this are multiple: non-immunogenic tumors, immunosuppressive tumor microenvironment or defects in immune cells trafficking to the tumor sites being some of the most frequent. Current progress in adoptive cell therapies could offer a way to overcome these hurdles and bring effective immune cells to the tumor site. In this review, we discuss advantages, limits and future perspectives of adoptive cell therapy (ACT) in thoracic malignancies from lymphokine-activated killer cells (LAK), cytokine-induced killer cells (CIK), natural killer cells (NK), dendritic cells (DC) vaccines and tumor-infiltrating lymphocytes (TILs) to TCR engineering and CARs. Trials are still in their early phases, and while there may still be many limitations to overcome, a combination of these different approaches with ICBs, chemotherapy and/or radiotherapy could vastly improve the way we treat thoracic cancers.

Glycaemic index, glycaemic load and cancer risk: results from the prospective NutriNet-Santé cohort.

BACKGROUND: Evidence is accumulating that high dietary glycaemic index (GI) and glycaemic load (GL) are potential risk factors for several metabolic disorders (e.g. type-2 diabetes, cardiovascular diseases), but remains limited concerning cancer risk. Although, mechanistic data suggest that consuming high-GI foods may contribute to carcinogenesis through elevated blood glucose levels, insulin resistance or obesity-related mechanisms. Our objective was to study the associations between dietary GI/GL and cancer. METHODS: In total, 103 020 French adults (median age = 40.2 years) from the NutriNet-Santé cohort (2009-2020) with no cancer or diabetes at baseline were included (705 137 person-years, median follow-up time = 7.7 years). Repeated 24-h dietary records linked with a detailed food-composition table (>3500 food/beverage items). We computed the average dietary GI and GL at the individual level. Associations between GI, GL, contribution of low- and medium/high-GI foods to energy and carbohydrate intake and cancer risk (overall, breast, prostate and colorectal) were assessed using multivariable Cox proportional-hazard models. RESULTS: Higher dietary GL was associated with higher overall cancer risk [n = 3131 cases, hazard ratios (HRs) for sex-specific quintile 5 vs 1 = 1.25, 95% confidence interval (CI) = 1.03-1.52; Ptrend = 0.008] and specifically postmenopausal breast cancer (n = 924, HRQ5vs.Q1 = 1.64, 95% CI = 1.06-2.55; Ptrend = 0.03). A higher contribution of low-GI food/beverages to energy intake was associated with lower cancer risk whereas a higher contribution of medium/high-GI items to energy intake was positively associated with higher risk of overall, breast and postmenopausal breast cancers (Ptrend ≤ 0.02). CONCLUSIONS: These results support a possible impact of GI/GL on cancer risk. If confirmed in other populations and settings, dietary GI/GL could be considered as modifiable risk factors for primary cancer prevention.

Endobronchial Seeding of Squamous Lung Carcinoma with Mediastinal Lymph Involvement Node after EBUS: A Case Report.

In locally advanced non-small-cell lung cancer (NSCLC), mediastinal staging is the cornerstone of the therapeutic decision and echoendoscopy is the most practiced exam to assess the lymph node involvement. We describe a rare case of endobronchial involvement by cells originating from a metastatic lymph node after endobronchial ultrasound (EBUS). A 64-year-old man was diagnosed with a squamous cell lung cancer with mediastinal nodal involvement proven by EBUS. The patient received neoadjuvant chemotherapy with partial response and was scheduled for a lobectomy. Before surgery, a fibroscopy was performed which demonstrated a 1-cm polypoid lesion settled on the internal face of the main right bronchus corresponding to the EBUS puncture site. The histological analysis confirmed tumoral cell in this lesion. The patient was rejected for surgery and undergo chemoradiation. This case highlights the need for a careful endoscopic control before surgical resection in case of prior positive EBUS followed by an interval of time.

A Pragmatic Study Evaluating NEPA Versus Aprepitant for Prevention of Chemotherapy-Induced Nausea and Vomiting in Patients Receiving Moderately Emetogenic Chemotherapy.

BACKGROUND: Neurokinin (NK) 1 receptor antagonists (RAs), administered in combination with a 5-hydroxytryptamine-3 (5-HT3 ) RA and dexamethasone (DEX), have demonstrated clear improvements in chemotherapy-induced nausea and vomiting (CINV) prevention over a 5-HT3 RA plus DEX. However, studies comparing the NK1 RAs in the class are lacking. A fixed combination of a highly selective NK1 RA, netupitant, and the 5-HT3 RA, palonosetron (NEPA), simultaneously targets two critical antiemetic pathways, thereby offering a simple convenient antiemetic with long-lasting protection from CINV. This study is the first head-to-head NK1 RA comparative study in patients receiving anthracycline cyclophosphamide (AC) and non-AC moderately emetogenic chemotherapy (MEC). MATERIALS AND METHODS: This was a pragmatic, multicenter, randomized, single-cycle, open-label, prospective study designed to demonstrate noninferiority of single-dose NEPA to a 3-day aprepitant regimen in preventing CINV in chemotherapy-naive patients receiving AC/non-AC MEC in a real-life setting. The primary efficacy endpoint was complete response (no emesis/no rescue) during the overall (0-120 hour) phase. Noninferiority was achieved if the lower limit of the 95% confidence interval (CI) of the difference between NEPA and the aprepitant group was greater than the noninferiority margin set at -10%. RESULTS: Noninferiority of NEPA versus aprepitant was demonstrated (risk difference 9.2%; 95% CI, -2.3% to 20.7%); the overall complete response rate was numerically higher for NEPA (64.9%) than aprepitant (54.1%). Secondary endpoints also revealed numerically higher rates for NEPA than aprepitant. CONCLUSION: This pragmatic study in patients with cancer receiving AC and non-AC MEC revealed that a single dose of oral NEPA plus DEX was at least as effective as a 3-day aprepitant regimen, with indication of a potential efficacy benefit for NEPA. IMPLICATIONS FOR PRACTICE: In the absence of comparative neurokinin 1 (NK1 ) receptor antagonist (RA) studies, guideline committees and clinicians consider NK1 RA agents to be interchangeable and equivalent. This is the first head-to-head study comparing one NK1 RA (oral netupitant/palonosetron [NEPA]) versus another (aprepitant) in patients receiving anthracycline cyclophosphamide (AC) and non-AC moderately emetogenic chemotherapy. Noninferiority of NEPA versus the aprepitant regimen was demonstrated; the overall complete response (no emesis and no rescue use) rate was numerically higher for NEPA (65%) than aprepitant (54%). As a single-dose combination antiemetic, NEPA not only simplifies dosing but may offer a potential efficacy benefit over the current standard-of-care.

Budget Impact Analysis of Fixed Dose Versus Weight-Based Dosing Regimen of Nivolumab and Pembrolizumab in the Treatment of Non-Small Cell Lung Cancer.

In 2018, dosing regimens of the two most prescribed immune check point inhibitors (ICI), nivolumab (Opdivo®) and pembrolizumab (Keytruda®), in the treatment of lung cancer were changed from weight-based dosing to fixed dosing. The aim of this study was to compare the economic impact of this change in our university hospital group and then across Ile-de-France, the most inhabited French region. A budget impact analysis (BIA) has been performed on the French public health insurance data. The duration of treatment and the weight of the patients were calculated using data from the patients treated at our health facility and from clinical studies. The cost of treatment was calculated at the local level of our health facility and then for Ile-de-France. Our model demonstrates an additional cost of €550,115 in our hospital and €9,704,778 in Ile-de-France for a fixed dose prescription in 2018. In 2019, the BIA concluded an additional cost, according to the respective low and high assumptions, of €556,969 and €756,544 locally and € 10,201,027 to €14,486,141 for Ile-de-France for an equivalent efficacy between the two different drug dosing regimens of nivolumab and pembrolizumab. The adoption of the fixed dose regimen would lead, according to the least expensive hypothesis, to an additional cost of 26% for the ICI. These results encourage reflection on the strict adoption of this dosage modification. The option of maintaining the free choice between a prescription adapted to weight or in a fixed dose seems a relevant option and should be considered.

[Nomadism of patients treated by radiotherapy in Île-de-France: Does our health system have as much money to waste?] / Nomadisme des patients traités par radiothérapie en Île-de-France : notre système de santé a-t-il autant d'argent à gaspiller ?

PURPOSE: Human, material, and financial resources being limited, the organization of the care system must allow an efficient allocation of resources. The management of cancers leads to specific and repetitive care for which the reimbursement of transport costs represents a high cost. We carried out an analysis of the additional transport costs, linked to the care of patients in Île-de-France, in a center other than the radiotherapy center closest to their home. MATERIALS AND METHODS: Using data from the Île-de-France Regional Health Agency, we have created a model evaluating the additional cost linked to transport generated by the care of a radiotherapy patient far from his home. In order to take into account the uncertainties linked to the hypotheses made in the development of the model, we carried out deterministic and probabilistic sensitivity analyzes. RESULTS: In the base case, the additional annual cost related to transport was 841,176 euros in Île-de-France. The probabilistic sensitivity analysis reports a total annual additional cost of 2,817,481 euros. CONCLUSION: Our results are similar to a report from the General Inspectorate of Social Affairs published in July 2011, which then pointed to an additional cost of between 4 and 6 million euros annually. The long-term care of cancer patients from their homes contributes to a deterioration in the quality of life linked to travel times, a delay in the care of potential treatment complications, and the spread of infectious diseases, such as COVID-19, and bacteria resistant to antibiotics.

Total and added sugar intakes, sugar types, and cancer risk: results from the prospective NutriNet-Santé cohort.

BACKGROUND: Excessive sugar intake is now recognized as a key risk factor for obesity, type 2 diabetes, and cardiovascular diseases. In contrast, evidence on the sugar-cancer link is less consistent. Experimental data suggest that sugars could play a role in cancer etiology through obesity but also through inflammatory and oxidative mechanisms and insulin resistance, even in the absence of weight gain. OBJECTIVE: The objective was to study the associations between total and added sugar intake and cancer risk (overall, breast, and prostate), taking into account sugar types and sources. METHODS: In total, 101,279 participants aged >18 y (median age, 40.8 y) from the French NutriNet-Santé prospective cohort study (2009-2019) were included (median follow-up time, 5.9 y). Sugar intake was assessed using repeated and validated 24-h dietary records, designed to register participants' usual consumption for >3500 food and beverage items. Associations between sugar intake and cancer risk were assessed by Cox proportional hazard models adjusted for known risk factors (sociodemographic, anthropometric, lifestyle, medical history, and nutritional factors). RESULTS: Total sugar intake was associated with higher overall cancer risk (n = 2503 cases; HR for quartile 4 compared with quartile 1: 1.17; 95% CI: 1.00, 1.37; Ptrend = 0.02). Breast cancer risks were increased (n = 783 cases; HRQ4vs.Q1 = 1.51; 95% CI: 1.14, 2.00; Ptrend = 0.0007). Results remained significant when weight gain during follow-up was adjusted for. In addition, significant associations with cancer risk were also observed for added sugars, free sugars, sucrose, sugars from milk-based desserts, dairy products, and sugary drinks (Ptrend ≤ 0.01). CONCLUSIONS: These results suggest that sugars may represent a modifiable risk factor for cancer prevention (breast in particular), contributing to the current debate on the implementation of sugar taxation, marketing regulation, and other sugar-related policies. This trial was registered at clinicaltrials.gov as NCT03335644.

Expression of angiopoietin-like 4 fibrinogen-like domain (cANGPTL4) increases risk of brain metastases in women with breast cancer.

BACKGROUND: Brain metastases challenge daily clinical practice, and the mechanisms by which cancer cells cross the blood-brain barrier remain largely undeciphered. Angiopoietin-like 4 (ANGPTL4) proteolytic fragments have controversial biological effects on endothelium permeability. Here, we studied the link between ANGPTL4 and the risk of brain metastasis in cancer patients. MATERIALS AND METHODS: From June 2015 to June 2016, serum samples from 113 cancer patients were prospectively collected, and ANGPTL4 concentrations were assessed. Using a murine model of brain metastases, we investigated the roles of nANGPTL4 and cANGPTL4, the two cleaved fragments of ANGPTL4, in the occurrence of brain metastases. RESULTS: An ANGPTL4 serum concentration over 0.1 ng/mL was associated with decreased overall-survival. Multivariate analyses found that only breast cancer brain metastases were significantly associated with elevated ANGPTL4 serum concentrations. 4T1 murine breast cancer cells were transfected with either nANGPTL4- or cANGPTL4-encoding cDNAs. Compared to mice injected with wild-type 4T1 cells, mice injected with nANGPTL4 cells had shorter median survival (p < 0.05), while mice injected with cANGPTL4 had longer survival (p < 0.01). On tissue sections, compared to wild-type mice, mice injected with nANGPTL4 cells had significantly larger surface areas of lung metastases (p < 0.01), and mice injected with cANGPTL4 had significantly larger surface areas of brain metastases (p < 0.01). CONCLUSIONS: In this study, we showed that a higher expression of Angiopoietin-like 4 Fibrinogen-Like Domain (cANGPTL4) was associated with an increased risk of brain metastases in women with breast cancer.

Development, validation and clinical impact of a prediction model for 6-month mortality in older cancer patients: the GRADE.

BACKGROUND: To develop, validate, and assess the clinical impact of a clinical score to predict a 6-month mortality risk among older cancer patients. RESULTS: The mean age was 81.2 ± 6.1 years (women: 54%, various cancers, metastatic cancer: 45%). The score, namely the GRADE, included two geriatric variables (unintentional weight loss, impaired mobility), two oncological variables (cancer site, cancer extension), and exclusively supportive care. Up to a 14% risk of early death, the decision curves suggest that cancer treatment should be instated. CONCLUSION: We have developed and validated a simple score, easy to implement in daily oncological practice, to predict early death among older cancer patients which could guide oncologists in their treatment decisions. METHODS: 603 outpatients prospectively included in the Physical Frailty in Elderly Cancer patients cohort study. We created a multivariate prediction model by evaluating the strength of the individual components of the Geriatric Assessment regarding risk of death at 6 months. Each component was evaluated by univariate analysis and the significant variables (P ≤ 0.20) were carried on as covariates in the multivariate cox proportion hazard analysis. The beta coefficients from the model were used to build a point-based scoring system. Clinical impact was assessed using decision curves.

Comparison of Mobility Indices for Predicting Early Death in Older Patients With Cancer: The Physical Frailty in Elderly Cancer Cohort Study.

BACKGROUND: To assess and compare the ability of five mobility indices to predict 6-month mortality in older patients with cancer. METHODS: All consecutive ambulatory older patients with cancer referred for a geriatric assessment before a cancer treatment decision were included in a prospective two-center cohort study (Physical Frailty in Elderly Cancer) between 2013 and 2017. The mobility indices compared were the short physical performance battery, gait speed, hand grip strength, the one-leg stance balance test, and repeated falls. The primary endpoint was 6-month overall mortality. The adjusted hazard ratio (95% confidence interval [CI]) for each mobility index was estimated using a multivariate Cox proportional hazard model adjusted for sex, the Cumulative Illness Rating Scale for Geriatrics, the body mass index, cancer site/extension, and the provision of supportive care alone. The models' predictive performances were assessed in terms of Harrell's C index, net reclassification improvement, and the standardized net benefit. RESULTS: A total of 603 patients included (mean age: 81.2 ± 6.1 years; women: 54%; metastatic cancer: 45%). In multivariate analyses, an impairment in any of the mobility indices (with the exception of repeated falls) was independently associated with 6-month mortality following a geriatric assessment; the adjusted hazard ratio [95% CI] ranged from 2.35 [1.34-4.13] for the one-leg stance balance (C index: 0.74) to 3.03 [1.93-4.76] for the short physical performance battery (C index: 0.77). For each mobility index, inclusion in the multivariate model improved significantly the latter's prediction of 6-month mortality. CONCLUSIONS: Among mobility tests, short physical performance battery had the best discriminative value for predicting 6-month mortality in older patients with cancer.

Monitoring anti-PD-1-based immunotherapy in non-small cell lung cancer with FDG PET: introduction of iPERCIST.

BACKGROUND: Immunotherapy represents a new therapeutic approach in non-small cell lung carcinoma (NSCLC) with the potential for prolonged benefits. Because of the systemic nature and heterogeneity of tumoral diseases, as well as the immune restoration process induced by immunotherapy, the assessment of therapeutic efficacy is challenging, and the role of FDG PET is not well established. We evaluated the potential of FDG PET to monitor NSCLC patients treated with a checkpoint inhibitor. RESULTS: This was a retrospective analysis of 28 NSCLC patients treated with nivolumab, a programmed cell death 1 (PD-1) blocker. All patients underwent a PET scan before treatment (SCAN-1) and another scan 2 months later (SCAN-2). Disease progression was assessed by immune PET Response Criteria in Solid Tumors (iPERCIST), which was adapted from PERCIST; and the immune Response Evaluation Criteria in Solid Tumors (iRECIST). iPERCIST is a dual-time-point evaluation of "unconfirmed progressive metabolic disease" (UPMD) status at SCAN-2. UPMD at SCAN-2 was re-evaluated after 4 weeks with SCAN-3 to confirm PMD. Patients with complete/partial metabolic response (CMR or PMR) or stable metabolic disease (SMD) at SCAN-2 or -3 were considered responders. Patients with UPMD confirmed at SCAN-3 were considered non-responders. The Kaplan-Meier method was used to estimate survival. At SCAN-2, we found 9/28 cases of PMR, 4/28 cases of SMD, 2/28 cases of CMR, and 13/28 cases of UPMD. Four of the 13 UPMD patients were classified as responders at SCAN-3 (PMR n = 1, SMD n = 3). The remaining nine UPMD patients were classified as non-responders due to clinical degradation, and treatment was stopped. The median follow-up was 16.7 months [3.6-32.2]. Responders continued treatment for a mean of 10.7 months [3.8-26.3]. Overall survival was longer for responders than that for non-responders (19.9 vs. 3.6 months, log rank p = 0.0003). The 1-year survival rates were 94% for responders and 11% for non-responders. A comparison with iRECIST showed reclassification in 39% (11/28) of patients with relevant additional prognostic information. CONCLUSIONS: iPERCIST dual-time-point evaluation might be a powerful tool for evaluating anti-PD-1-based immunotherapy, with the ability to identify patients who can benefit most from treatment. The prognostic value of iPERCIST criteria should be confirmed in large prospective multicentric studies.
